The complaining resident no doubt is a migrant. He should contemplate moving back to where he came from. Frogs were first to settle in Sanya, long before troublesome and environmentally upsetting humans arrived.

Frogs are man's best friend, they keep the ecosystem in balance by eating up pests like flies and mosquitoes.
Hw audacious of this resident to complain about frog noise when the Chinese are even more noisy than frogs, with their screaming when they talk to each other at close range and into cellphones.
